Abstract
Description
Technical Field
[0001] This utility model relates to the field of sway simulation technology, and in particular to a ship sway simulation test device. Background Technology
[0002] In the field of ship design and research, ships are affected by factors such as wind and waves when sailing at sea, which causes them to sway. This is crucial to the stability of the ship, the reliability of equipment operation, and the safety of personnel. Therefore, sway simulation tests are needed to test the relevant performance of the ship.
[0003] In the existing technology, traditional sway test equipment generally suffers from two major technical bottlenecks: First, the sway amplitude adjustment relies on manual adjustment of the mechanical structure, which makes it difficult to achieve dynamic simulation under different sea conditions, resulting in a large deviation between the test data and the actual working conditions; Second, the model fixing device mostly adopts a rigid clamping structure and lacks a buffer design, which makes the model prone to loosening or even falling off in high-frequency sway tests, which not only affects the test accuracy, but also poses the risk of equipment damage and safety accidents. Therefore, this application provides a ship sway simulation test equipment to meet the needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a ship sway simulation test device, which solves the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A ship swaying simulation test device includes a base, a support plate fixedly connected to the top of the base, a swaying platform disposed on the inner side of the support plate, rotating rods fixedly connected to both sides of the swaying platform, a mounting frame fixedly connected to the side of the support plate, a swaying assembly for performing swaying experiments on the ship, the swaying assembly being connected to the mounting frame, and a fixing assembly for fixing the position of the ship on the test platform, the fixing assembly being connected to the swaying platform.
[0007] Optionally, the rocking assembly includes a drive motor fixedly connected to the inside of the mounting frame, a Z-shaped rotating rod fixedly connected to the output end of the drive motor, a mounting rod fixedly connected to the top of the mounting frame, a sector gear rotatably connected to the outside of the mounting rod, and a gear fixedly connected to one end of the rotating rod extending to the outside of the support plate.
[0008] Optionally, a limiting strip is fixedly connected to the bottom of the mounting rod, and the Z-shaped rotating rod extends to one end of the limiting strip and is slidably connected to the limiting strip.
[0009] Optionally, the overall profile of the sector gear is sector-shaped, and the sector gears are meshed with each other.
[0010] Optionally, the fixing component includes a limiting plate fixedly connected to one side of the swing platform, a limiting groove is formed on the inner side of the limiting plate, a threaded screw is fixedly connected to the outer side of the swing platform, a clamping plate is slidably connected to the outer side of the threaded screw, and a rubber pad is fixedly connected to the inner side of the swing platform near the clamping plate.
[0011] Optionally, the threaded screw is threaded to the outer side with a limit bolt, and the clamping plate is fixedly connected to both sides with sliders, and the sliders are slidably connected to the limit grooves.
[0012] Optionally, the swing platform is located inside the support plate, and the swing platform and the support plate are rotatably connected by a rotating rod.
[0013] Beneficial effects:
[0014] In the above scheme, by setting up a swing component, ship swing test can be realized. The drive motor drives the Z-shaped rotating rod to rotate, and under the action of the limit bar, the sector gear swings back and forth. Through gear transmission, the rotating rod drives the swing platform to swing. Furthermore, controlling the speed of the drive motor can change the swing amplitude, which can simulate swing states of different amplitudes and improve the comprehensiveness of ship testing.
[0015] By setting up fixing components, the position of the model hull can be effectively fixed. The hull is placed on the rubber pad inside the rocking platform, and the clamping plate is pushed to move along the limiting slide and fit against the bottom plate of the model. The clamping plate is then fixed by the limiting bolt. This can prevent the model from shifting, tipping over or even falling off due to violent shaking, thus preventing damage to the model and safety hazards to the test equipment or operators.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1 and Figure 3 As shown, an embodiment of this utility model provides a ship sway simulation test device, including a base 1, a support plate 2 fixedly connected to the top of the base 1, a sway platform 3 arranged on the inner side of the support plate 2, rotating rods 4 fixedly connected to both sides of the sway platform 3, a mounting frame 5 fixedly connected to the side of the support plate 2, a sway assembly 6, the sway assembly 6 being used to perform sway experiments on the ship, the sway assembly 6 being connected to the mounting frame 5, and a fixing assembly 7, the fixing assembly 7 being used to fix the position of the ship on the test platform, the fixing assembly 7 being connected to the sway platform 3, the sway platform 3 being located inside the support plate 2, and the sway platform 3 being rotatably connected to the support plate 2 through the rotating rods 4. The ship sway simulation test device provided by this application can not only realize the ship sway test through the sway assembly 6, but also change the sway amplitude by controlling the speed of the drive motor 601, which is convenient for simulating different amplitude sway states and improving the overall performance of ship testing. In addition, the fixing assembly 7 is used to fix the model ship hull, avoiding the possibility that the model may shift, tip over or even fall off due to violent shaking if it is not fixed, which would not only damage the model itself, but also pose a safety hazard to the test equipment or operators.
[0025] In this embodiment, as Figures 2 to 5As shown, the rocking assembly 6 includes a drive motor 601 fixedly connected to the inner side of the mounting frame 5. A Z-shaped rotating rod 602 is fixedly connected to the output end of the drive motor 601. A mounting rod 604 is fixedly connected to the top of the mounting frame 5. A sector gear 605 is rotatably connected to the outer side of the mounting rod 604. A gear 603 is fixedly connected to one end of the rotating rod 604 extending to the outer side of the support plate 2. A limit strip 606 is fixedly connected to the bottom of the mounting rod 604, and the Z-shaped rotating rod 602 extends to the inner side of the limit strip 606 and is slidably connected to the limit strip 606. The sector gear 605 has a sector-shaped overall profile, and the sector gear 605 meshes with the gear 603. In use, after the model ship is fixed, the rocking assembly 6 is rocked by turning on the drive motor 601. The drive motor 601 drives the Z-shaped rotating rod 602 to rotate along the inner side of the limiting strip 606, causing the limiting strip 606 to swing left and right, which in turn drives the sector gear 605 to swing back and forth along the outer side of the mounting rod 604. When the sector gear 605 swings, the bottom of the sector gear 605 meshes with the gear 603. The back and forth rotation of the gear 603 causes the rotating rod 4 to drive the model ship inside the swing platform 3 to swing back and forth inside the support plate 2. The swing amplitude can be changed by controlling the speed of the drive motor 601, which is convenient for simulating swing states of different amplitudes, improving the overall performance of ship testing, and thus completing the simulation experiment of ship swing.
[0026] In this embodiment, as Figures 1 to 6 As shown, the fixing component 7 includes a limiting plate 701 fixedly connected to one side of the rocking platform 3. A limiting groove 702 is formed on the inner side of the limiting plate 701. A threaded rod 703 is fixedly connected to the outer side of the rocking platform 3. A clamping plate 704 is slidably connected to the outer side of the threaded rod 703. A rubber pad 707 is fixedly connected to the inner side of the rocking platform 3 near the clamping plate 704. A limiting bolt 705 is threadedly connected to the outer side of the threaded rod 703. Slider blocks 706 are fixedly connected to both sides of the clamping plate 704, and the sliders 706 are slidably connected to the limiting groove 702. When it is necessary to fix the model hull, the hull is fixed by... Place the model inside the rocking platform 3 so that the two bottom plates of the hull are on the rubber pad 707. Then push the clamping plate 704 so that it moves downward along the limiting groove 702, making the clamping plate 704 fit against the bottom plate of the model. Then rotate the limiting bolt 705 so that the limiting bolt 705 presses down on one end of the clamping plate 704 along the outer thread of the threaded screw 703, thereby fixing the position of the clamping plate 704 and fixing the position of the model. This prevents the model from shifting, tipping, or even falling off due to violent shaking, which would not only damage the model itself but also pose a safety hazard to the test equipment or operators.
[0027] The working principle of the technical solution provided by this utility model is as follows: During use, the hull is placed inside the rocking platform 3, so that the two bottom plates of the hull are on the rubber pad 707. At this time, the clamping plate 704 is pushed, causing it to move downwards along the limiting groove 702, making the clamping plate 704 fit against the model's bottom plate. Then, the limiting bolt 705 is rotated, causing it to press downwards along the outer thread of the threaded screw 703 against one end of the clamping plate 704, thus fixing the position of the clamping plate 704 and securing the model's position. This prevents displacement, tipping, or even detachment due to violent shaking, which could damage the model itself and pose safety hazards to the testing equipment or operators. After setting, by turning on the drive motor 601, the output shaft of the drive motor 601 drives the Z-shaped rotating rod 602 to rotate along the inner side of the limit bar 606, causing the limit bar 606 to swing left and right, driving the sector gear 605 to swing back and forth along the outer side of the mounting rod 604. When the sector gear 605 swings, the bottom of the sector gear 605 meshes with the gear 603. Through the back and forth rotation of the gear 603, the rotating rod 4 drives the model ship inside the swing platform 3 to swing back and forth inside the support plate 2. By controlling the speed of the drive motor 601, the swing amplitude can be changed, which is convenient for simulating swing states of different amplitudes, improving the overall performance of ship testing, and thus completing the simulation experiment of ship swing.
